Cutting to the Core
In our July issue, Eos looks at the collection, study, and storage of cores—from sediment drilled up from the age of the dinosaurs to tree rings as big as a house.
Cores 3.0: Future-Proofing Earth Sciences’ Historical Records
Core libraries store a treasure trove of data about the planet’s past. What will it take to sustain their future?
Amazon Forests Are Turning into Savannas
Floodplain forests have low resilience to repeated exposure to wildfires. As climate change increases the instances of fires, forests may transform to less productive grassland ecosystems.
Dry Soils Enhanced the 2018 Heatwave in Northern Europe
A range of observations show that a shift in land-atmosphere coupling exacerbated the hot drought experienced in Europe in 2018.
A Warming World Threatens Colombia’s Coffee Future
Colombia is the second-largest producer of Arabica coffee, but changing climate, soil, and precipitation patterns are already altering the harvest volume, production techniques, and even the taste of coffee.
Turf’s Dirty Little Secret
Greenhouse gas emissions from sports fields may be scoring points for climate change.
Soil Chips Help Scientists Spy on Fungal Navigation
Soil chips provide a micrometer-resolution window into life underfoot, shedding light on how fungi behave when navigating soil’s mazes.
